Objective To assess the outcomes of a protocol led same day discharge for elective tonsillectomy patients. Design A retrospective series of all tonsillectomies performed from January 2018 to May 2023 at a tertiary hospital in Adelaide, Australia. The primary outcome was rate of readmission within 24 hours for same day surgery compared to hospital stay tonsillectomy patients. Secondary outcomes included post tonsillectomy haemorrhage (PTH). The patients were identified through the hospital’s tonsillectomy database, with subsequent review of medical charts to extract patient demographics, readmission and PTH data. Results During the study period, n=1658 elective tonsillectomies were performed. 664 patients (40.0%) were discharged the same day following tonsillectomy. 30% (199) of day surgery patients were paediatric (under 18 years old). The readmission rate within 24 hours was comparable between the two groups (0.60% for day surgery and 0.64% for those who stayed overnight in hospital). X 2(1, N=1600)=0.009, p=.9244. The primary PTH rate for day surgery patients was 0.3%, with a relative risk of 0.5. X 2(1, N=1658)=0.751, p=.3862. Conclusion The readmission rate within 24 hours for same day tonsillectomies was comparable to patients who stayed in hospital for one or more days post operatively. The low readmission rate and primary post-tonsillectomy haemorrhage within 24 hours post day surgery tonsillectomy for patients indicates that same day tonsillectomy is safe and feasible to implement.
